K&L Gates has advised Japan Airlines on a purchase of aircraft from Airbus SAS, worth as much as $9.5 billion.

JAL has agreed to acquire 31 of Airbus’s upcoming A350 passenger jet, with the option to purchase a further 25 in the future. The company plans to introduce the new planes in early 2019. The list price for the 31 aircraft ordered is $9.5 billion though manufacturers typically give substantial discounts on large orders.

The deal has been hailed as a landmark for Europe’s Airbus, as JAL and the other major Japanese airline, All Nippon Airways Co. Ltd., had long been loyal customers of U.S. aircraft manufacturer Boeing Co.

Keiji Isaji, Atsushi Yamashita, and Robert Melson were the lead Tokyo partners advising JAL. They were supported by London partner Trevor Beadle.

Airbus, as on many of its aircraft sales, used in-house counsel in negotiations with JAL.
